A dataset of acoustic measurements from soundscapes collected worldwide during ...
Marques, J. TiagoPolitical responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium of 261 contributors from 35 countries brought together by the Silent Cities project built a unique soundscape recordings collection to report on local acoustic changes in urban areas. We present this collection here, along with metadata including observational descriptions o...

Mediterranean temporary pond restoration invcreases bat species richness but no...
Silva, Joana; Cruz, Carla; Marques, J. TiagoClimate change scenarios predict a continued decrease in rainfall across the Mediterranean regions in the next years, emphasizing concerns about water scarcity. The ongoing destruction, modification, and drainage of wetland habitats further intensifies this risk to the landscape. Ponds are vulnerable aquatic habitats that supply essential ecosystem services and provide foraging and drinking resources to bats. T...
Acoustic detection and occupancy models: A systematic review with insights for ...
Martins, Frederico; Segurado, Pedro; Marques, J. TiagoWildlife management requires monitoring to infer spatiotemporal changes in the distribution or abundance of species and communities of organisms. Technological advancements have increasingly facilitated monitoring species through new data collection methods. Such technological advancements include small-sized acoustic recording devices that can record a wide range of sound frequencies, making them especially su...
Vegetation canopy height shapes bats’ occupancy: a remote sensing approach
Martins, Frederico C.; Godinho, Sérgio; Nuno, Guiomar; Denis, Medinas; Hugo, Rebelo; Pedro, Segurado; Marques, J. TiagoAnthropogenic activities have significantly altered land cover on a global scale. These changes often have a negative effect on biodiversity, limiting the distribution of species. The extent of the effect on species’ distribution depends on the landscape composition and configuration at a local and landscape level. To better understand this effect on a large scale, we evaluated how land cover and vegetation str...
Monitoring mulch-based solutions to reduce runoff and erosion in a variety of l...
Canedo, João; Coelho, Luisa; Basch, Gottlieb; Cabrita, Maria João; Cachapa, Filipa; Caldeira, Filipa; Gonzalez-Pelayo, Óscar; Marques, J. TiagoSoil erosion is a critical socio-environmental problem for rural Mediterranean ecosystems and landscapes. Erosion inflicts multiple, serious damages in agro-ecosystems, including vineyards and olive groves, and also in other semi-natural ecosystems such as the Montado (cattle-sheep pastureland combined with Quercus sp. trees). In particular, erosion reduces the water storage capacity, soil organic matter, nutri...
Gathering information of cryptic species: Insights from Integrated Occupancy M...
Martins, Frederico; Barros, Paulo; Cabral, João; Segurado, Pedro; Marques, J. TiagoEffective conservation planning relies on an adequate understanding of species occurrence at both individual and community levels. However, detecting some species presents a challenge, and the efficiency of sampling methods varies. Data integration from multiple methods is a natural solution to address these issues and enhance species parameter estimation. This study explores the benefits of combining sampling ...

Artificial permanent ponds are valuable for bats: a comparison with temporary p...
Ribeiro-Silva, Joana; Pinto-Cruz, Carla; Mira, António; Marques, J. TiagoPonds are crucial habitats for bats in Mediterranean regions, providing significant sources of food and drinking water. However, the intensification of land use and the increase in arid landscapes are threatening these ecosystems, leading to a significant decline in water availability. Our aim is to assess the influence of biotic and abiotic pond features on bat communities, with a focus on the hydrological reg...

Medinas, Denis; Ribeiro, Vera; Barbosa, Soraia; Valerio, Francesco; Marques, J. Tiago; Rebelo, Hugo; Paupério, Joana; Santos, Sara; Mira, AntónioThe effective management of species with small and fragmented populations requires an in-depth understanding of how the effects of human-induced habitat disturbance shape the structure and gene flow at fine spatial scales. Identification of putative environmental barriers that affect individual exchange among subpopulations is imperative to prevent extinction risks. Here, we investigated how landscape affects t...
